In the conventional examples described in the paragraphs 0003 to 0005, the release wire is taken out from the drain outlet at the time of construction. At this time, the release wire jumps out from the drain outlet, and the bearing part of the wire receiving part and the release wire are Connection is very difficult for the installer. Furthermore, in this conventional example, it is necessary to make a rotational connection by screwing the end of the release wire and the bearing portion of the wire receiving portion with a screw body even though the allowance of the release wire from the drain outlet is short. It was very difficult for the installers. In addition, it is necessary to perform all such work in a narrow bathtub, so it is more difficult to construct, and in the worst case, the release wire may be pulled excessively during construction, causing the release wire to be bent, etc. There was something to do.
Further, in the conventional examples described in the paragraphs 0006 to 0008, the end of the release wire is pulled out from the bearing portion in the drain outlet, and further inserted into the bearing portion, and then the E-ring is attached to the bearing portion to prevent the release wire. For this reason, there is a lot of trouble at the time of construction, and since the E-ring is placed on the construction site and attached, there is a possibility that the E-ring may be lost at the site. This E-shaped ring is a very small part and is unlikely to be found if it is lost. If it is dropped inside the drain, it can be removed without removing the bathtub and disassembling the drain. There wasn't. Also in this conventional example, the release wire is taken out from the drain outlet at the time of construction, but at this time the release wire jumps out from the drain outlet and the connection between the bearing part of the wire receiving part and the release wire is for the installer. It will be very difficult. Further, in this conventional example, the release wire and the bearing portion must be connected even though the release wire has a short protruding margin from the drain port. Therefore, it was very difficult for the installer. In addition, it is necessary to perform all such work in a narrow bathtub, so it is more difficult to construct, and in the worst case, the release wire may be pulled excessively during construction, causing the release wire to be bent, etc. There was something to do.
In the conventional examples described in the paragraphs 0009 to 0011, one end of the release wire is pulled out from the bearing portion in the drain port, and the release wire and the wire receiving portion are connected. The end portion of the release wire is used as the bearing portion. Since the cap body is crowned on the bearing portion after being inserted and both are prevented from being detached, there is a lot of trouble at the time of construction, and the cap body is attached at the construction site, so there is a possibility that the cap body may be lost at the site. This cap is a very small part that is unlikely to be found if lost, and if it is dropped inside the drain, it cannot be removed without removing the bathtub again and disassembling the drain. It was. Further, in this conventional example, the engagement between the cap body and the bearing portion, the release wire and the bearing portion is the engagement connection by the engagement claw and the engagement port, but the elasticity of the engagement claw is weak or the installer is neat. It may not be confirmed whether the cap body has been crowned on the bearing part, etc., and the release wire engagement claw and the cap body may not be properly engaged. In such a case, the release wire is properly connected to the drain outlet. Since it is the same as not being fixedly arranged at the center, there has been a problem in that the release wire falls into the drainage port during use by the user, and the valve body cannot be opened and closed normally.
